HEAT PUMP CYCLE DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18602846 titled 'HEAT PUMP CYCLE DEVICE

Simplified Explanation:

This patent application describes a heat pump cycle device that controls the pressure difference in the system to achieve optimal performance.

• The device includes a compressor, a branching unit, a heating unit, a depressurizing unit, a bypass passage, a flow-rate adjusting unit, a mixing unit, and a target pressure difference determining unit.
• The target pressure difference determining unit calculates a target pressure difference based on the difference between suctioned refrigerant pressure and discharge refrigerant pressure.
• The operation of the compressor, depressurizing unit, or flow-rate adjusting unit is controlled to maintain the pressure difference close to the target value.

Key Features and Innovation:

• Control system to adjust pressure difference for optimal performance.
• Target pressure difference calculation for efficient operation.
• Integration of various units to regulate the system effectively.

Potential Applications:

Original Abstract Submitted

A heat pump cycle device includes a compressor, a branching unit, a heating unit, a heating-unit-side depressurizing unit, a bypass passage, a bypass flow-rate adjusting unit, a mixing unit, and a target pressure difference determining unit. The target pressure difference determining unit determines a target pressure difference as a target value of a pressure difference determined by subtracting a suctioned refrigerant pressure from a discharge refrigerant pressure. An operation of at least one of the compressor, the heating-unit-side depressurizing unit, or the bypass flow-rate adjusting unit is controlled so that the pressure difference comes close to the target pressure difference.
